Hi Lookman, As suggested on the thread for your weekly (2) update, please consider making steps for things you would like me to test. If no steps are required then a brief description, and possibly sources for further information, might be useful (to me or anyone wanting to test and/or reproduce).
With regards to porting SCA to Android, please see comments inline below. Way to go on the community bonding period! I think you made substantial progress and got up to speed with your project. Now we have the official start of GSoC coming up this Thursday May 23rd. So, congrats and keep up the cool stuff!!

I'm not sure if sources are available, but in case they are not we might be able to get them from the author, Taras Puchko. Taras was very helpful last year on my project, and so you might want to consider contacting him through the Android developer mailing list. Of course, I'm also happy to help with any retrotranslator'ing, and so we can discuss if needed, before seeking help elsewhere.

Despite significant help from Adriano, I could not get the modules completely running on Android. Every time there was some API or non-supported feature that got in the way. However, that may no longer be the case now, especially since Android is now fully open-source and new versions have been released. I encourage you to analyze this alternative, and choose the one you find to be most promising. > > > -- > Best Regards > > Lookman SANNI > http://blog.lookouster.org > MSBI Intern at Umanis Tours Services; > -- best, -oscar Oscar Castañeda http://people.apache.org/~ocastaneda<http://people.apache.org/%7Eocastaneda>
